Order this document by MC33193/D MC33193 Advance Information Automotive Direction Indicator The MC33193 is a new generation industry standard UAA1041 “Flasher”.
It has been developed for enhanced EMI sensitivity, system reliability, and improved wiring simplification.
The MC33193 is pin compatible with the UAA1041 and UAA1041B in the standard application configuration as shown in Figure 9, without lamp short circuit detection and using a 20 mΩ shunt resistor.
The MC33193 has a standby mode of operation requiring very low standby supply current and can be directly connected to the vehicle’s battery.
It includes an RF filter on the Fault detection pin (Pin 7) for EMI purposes.
